Grepping for "GLOBAL__I" gives this:

kornerr@koren:/usr/local/lib$ nm libHorde3D.so  | grep GLOBAL__I

According to man nm, t is just text. I guess that means no global
constructors envolved.

Grepping for the function causing problem when -lGL is before -lHorde3D:

kornerr@koren:/usr/local/lib$ nm libHorde3D.so | grep "glCreateShader"
0000000000377aa8 B glCreateShader

According to man nm, the B means the symbol is in the uninitialized
data section. May be that's the reason?
